First of all, good work!  Noone has ever done this before, AFAIK.

Mechanically, yes.  Softwarewise, no.  Canon BJ does have some fonts
in its ROM, but Apple SW has no fonts if I'm not mistaken.  Everyting
is sent to the printer as bitmap.  DW is more of an ordinary serial
dot-impact printer, isn't it?
